Pharrell Williams' 'Happy' is now the UK's most downloaded song

Pharrell Williams' smash-hit 'Happy' is now the UK's most downloaded song of all time.

Williams, who released his new album G I R L (which you can preview on the right-hand side of the page) earlier this year, has moved past Robin Thicke's 'Blurred Lines' with 'Happy', which has has sold 1.62 million copies since it was released in June last year as part of the Despicable Me 2soundtrack.

Speaking to the Official Charts Company about the milestone, Williams said: "I would just like to say thank you, first and foremost, to the people, because the charts are determined by them. I have a lot to be thankful for because they’ve chosen these things and it’s resulted in 'Happy' being what it’s become.”

He continued: “The people of the UK have been so supportive of me over the years, allowing me to be an artist and allowing me to work with other people and supporting what it is that I do. That’s the lifeline, without them you’re just a musician with a couple of ideas but with them, that is the thing that changes everything when they get involved, your little idea can become something, so …thank you!’'

Pharell is currently in the middle of a full European tour and plays two shows at London's O2 Arena next month.
